Answer:
(E) 1
Step-by-step explanation:
2r+ (2r+3 ) < 11
Combine like terms
4r+3 < 11
Subtract 3 from each side
4r +3-3 < 11-3
4r < 8
Divide each side by 4
4r/4 < 8/4
r <2
The only possible choice is 1

Explanation:
________________________________________________
Set up the ratio as a fraction:
→ " 2/3 = 4/x " ; Solve for "x" (the age; in "years", of the "other child") ;
<u>Note</u>: GIven the ratios of two children is: 2:3 ; and there is a younger child among the two children; the number "2" would represent the "younger child; since there are 2 (two) children; and there are 2 (two) numbers in the given ratios; and among the 2 (two) numbers given in the ratio — which are: "2" and "3" ; the given number: "2" is LESS THAN the given number "3" ;
As such:
____________________________________________________
→ " 2/3 = 4/x " ; Solve for "x" ;
Cross-multiply;
2x = 3*4 ;
2x = 12 ;
Divide each side of the equation by "2" ;
to isolate "x" on one side of the equation; & to solve for "x" ;
2x/2 = 12/2 ;
to get:
_______________________________________________
" x = 6 "

Set up the ratio:
_____________________________________________
→ " 2/3 = 4/x " ; Solve for "x" ;
Recognize that: "2/3 = 4/6" ; and that: "x = 6" ;

Alternate method:
______________________________________________
Set up the ratio:
_______________________________________________
→ " 2/3 = 4/x " ; Solve for "x" ;
In the "numerator": → " 2 * [what value?] = 4 ? "
→ To find that value: " 4 ÷ 2 = "2 " .
As such: Multiply the given: "3" in the "denominator" by "2" ; to get:
_______________________________________________
"3 * 2 = "x" ; ↔ " x = 6 " .
